Claims

[Claims for Utility Model Registration] 1. Something that holds the vibrating piece and detects the relative position of the vibrating piece to the object based on a signal emitted when the end of the vibrating piece that is almost resonating comes into contact with the object. The vibrating element includes a vibrating element whose holding part is thicker than the thickness of the vibrating element, an AE sensor that is placed in contact with the holding part, and an electromagnet and a proximity sensor that face each other with the vibrating element positioned approximately in the center thereof. A vibrating piece type position detection device characterized by the following. 2. The vibrating piece type position detection device according to claim 1 of the utility model registration claim, in which the holding part is made of a non-conductive material and holds the vibrating piece. 3. A vibrating piece type position detection device according to claim 1 or 2 of the utility model registration claim, in which a small hole is provided in the holding part to prevent the vibrating piece from falling off. 4. A vibrating piece type position detection device according to any one of claims 1 to 3 of the claims for utility model registration, in which the width of the vibrating piece part that follows the holding part is narrower than the width of the vibrating piece other than that part.
